Organisers have decided the event will now be a virtual experience.
Open Doors is designed to give the public a look at what goes on behind the hoardings on construction sites up and down the country.
Last year 290 sites hosted visits taking more than 6,000 bookings.
Organisers Build UK said: “The mission of Open Doors has always been to welcome and showcase the industry to as many people as possible, but we need to make sure it is safe and responsible to do so.
“Thanks to the wonders of technology, we are taking Open Doors Digital and offering a range of remote options for visitors to learn more about construction and explore sites across the country.”
Build UK Project Manager Alice Cook said: “We would like to ask all employers to explore “Open Doors Goes Digital” and encourage all visitors to look at the options.
“In particular, schools can still utilise the spot in their timetable scheduled for an Open Doors site visit to explore the fantastic career opportunities available in construction.”
